Wiki has two sections on Sophie Scholl's page ("Activities of the White Rose" and "Legacy") that redundantly recount her last words. Redudant except that they don't match up.

One version is "It is such a splendid sunny day, and I have to go. But how many have to die on the battlefield in these days, how many young, promising lives. What does my death matter if by our acts thousands are warned and alerted. Among the student body there will certainly be a revolt."

2nd version is "How can we expect righteousness to prevail when there is hardly anyone willing to give himself up individually to a righteous cause? Such a fine, sunny day, and I have to go, but what does my death matter, if through us, thousands of people are awakened and stirred to action?"
